A Facebook scam disguised as an invite to view a leaked sex video allows cybercriminals to infect different users with different malware in a highly efficient ?polymorphic? attack that could end in bank fraud, invasion of privacy, or a wave of illicit porn advertising.

The scam starts with a Facebook post which features an alluring thumbnail, the first frame of the alleged sex tape....Users who click the link included in this post are told they must install a Divx plugin to actually view the video.
